AMC1 ML.A.302(c)(9) Aircraft maintenance programme    

CAA ORS9 Decision No. 1

ANNUAL REVIEW OF THE AMP

(a) During the annual review of the maintenance programme, as required by point ML.A.302(c)(9), the following should be taken into consideration:

(1) the results of the maintenance performed during that year, which may reveal that the current maintenance programme is not adequate;

(2) the results of the AR performed on the aircraft, which may reveal that the current maintenance programme is not adequate;

(3) revisions introduced on the documents affecting the programme basis, such as the ML.A.302(d) MIP or the DAH’s data;

(4) changes in the aircraft configuration, and type and specificity of operation;

(5) changes in the list of pilot-owners; and

(6) applicable mandatory requirements for compliance with Part 21, such as airworthiness directives (ADs), airworthiness limitations, certification maintenance requirements and specific maintenance requirements contained in the type certificate data sheet (TCDS).

(b) When reviewing the effectiveness of the AMP, the AR staff (or the CAMO/CAO staff if the review of the AMP is not performed in conjunction with an AR) may need to review the maintenance carried out during the last 12 months, including unscheduled maintenance. To this end, he or she should receive the records of all the maintenance performed during that year from the owner/CAMO/CAO.

(c) When reviewing the results of the maintenance performed during that year and the results of the AR, attention should be paid as to whether the defects found could have been prevented by introducing in the maintenance programme certain DAH’s recommendations, which were initially disregarded by the owner, CAMO or CAO.
